Read About Wireless Diagnostics. It will present a summary of your wireless environment and may suggest additional actions for you to pursue.MacBooks iMacs iPads AirPorts, OS X Mountain Lion, 28 years Apple!

Thank you so much for answering. I have tried the OS X: How to troubleshoot Wi-Fi connectivity and it has helped a lot. I will also read about wireless diagnostics and other related articles. Thanks again for your help and prompt answer. Maria
